Mike I own all of them, the ycs1 is perfect shape, but is under major cover at all times, the yz was a big time resoration job, it had no seat or tank, and the motor was rusted up, I have sence had the cyl. re-nicom coated, and rebuilt the complete motor. It was fun, but very costly !!! there arnt many of them around anymore, and I still need a stock seat base.( the seat base I hve is a remake, ) But yes, they are all mine.... l
